摘要

在大数据时代,电子数据发展迅速,逐渐取代了传统的纸质文件。在日常生活中,各种数据都以电子文档的形式保存。对此,人们加强了电子存管系统的开发。电子存储是指通过信息技术以电子数据的形式存储实际事件,以证明事件发生的时间和内容。它的应用场景非常广泛,如电子合同、网上交易、知识产权等。但是,由于电子数据的脆弱性,现有的电子数据存管系统存在一定的安全风险,其内容非常容易被篡改和破坏,造成存管信息的丢失。由于现有电子数据存管系统操作的复杂性,一些用户可能会因为操作不规范而降低存管信息的真实性。为了解决当前电子数据存储系统中存在的问题,本文设计了一种基于云计算和区块链技术的电子数据存储系统。云计算和区块链的数据存储是去中心化的,其内容不可篡改。能有效保证电子信息的完整性和安全性,更适合电子存储场景的需求。本文首先介绍了电子数据存储系统和云计算的发展,并通过云计算的任务调度模型对电子数据存储系统进行了优化。最后,通过实验验证了系统的可行性。数据表明,系统在电子数据采样点存储功能、待存储文件上传功能、已存储文件下载功能、已存储信息查看功能和文件存储与证书比对验证功能中的功能效率分别达到0.843、0.821、0.798、0.862和0.812。传统电子数据存管系统各功能的最终功能指标分别为0.619、0.594、0.618、0.597、0.622。该数据表明,基于云计算和区块链建模的电子数据存储系统可以有效管理电子数据,方便相关人员对电子数据进行验证。

Data storage query and traceability method of electronic certificate based on cloud computing and blockchain
In the age of big data, electronic data has developed rapidly and gradually replaced traditional paper documents. In daily life, all kinds of data are saved in the form of electronic documents. In this regard, people have strengthened the development of electronic depository system. Electronic storage refers to the storage of actual events in the form of electronic data through information technology to prove the time and content of events. Its application scenarios are very extensive such as electronic contracts, online transactions and intellectual property rights. However, due to the vulnerability of electronic data, the existing electronic data depository system has certain security risks, and its content is very easy to be tampered with and destroyed, resulting in the loss of depository information. Due to the complexity of the operation of the existing electronic data depository system, some users are likely to reduce the authenticity of the depository information due to the non-standard operation. In order to solve the problems existing in the current electronic data storage system, this paper designed an electronic data storage system based on cloud computing and blockchain technology. The data storage of cloud computing and blockchain was decentralized, and its content cannot be tampered with. It can effectively ensure the integrity and security of electronic information, which is more suitable for the needs of electronic storage scenarios. This paper first introduced the development of electronic data depository system and cloud computing, and optimized the electronic data depository system through the task scheduling model of cloud computing. Finally, the feasibility of the system was verified through experiments. The data showed that the functional efficiency of the system in the electronic data sampling point storage function, the upload of documents to be stored, the download of stored documents, the view of stored information function and the file storage and certificate comparison verification function has reached 0.843, 0.821, 0.798, 0.862 and 0.812 respectively. The final function indexes of each function of the traditional electronic data depository system were 0.619, 0.594, 0.618, 0.597 and 0.622 respectively. This data shows that the electronic data storage system based on cloud computing and blockchain modeling can effectively manage electronic data and facilitate relevant personnel to verify electronic data.
